Have you shot many coots or possums? Any recipe that works on coots and possums might be good enough to get your dog to eat the sage grouse. They are much like antelope in that they taste a lot better if given away to someone who you never expect to see again. Afterwards you can go to mass and do penance for being cruel to the guy you gave them to. If you are wishing your wife would give you a divorce you can take them home and bake them in the oven without turning on the vent fan.
